According to the endurance running hypothesis, long-distance running as in persistence hunting, a method still practiced by some hunter-gatherer groups in modern times, was likely the driving evolutionary force leading to the evolution of certain human characteristics. This hypothesis does not necessarily contradict the scavenging hypothesis: both subsistence strategies could have been in use – sequentially, alternating or even simultaneously.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The scavenging hypothesis is still practiced by which groups? 
Ah, so.. unanswerable

An individual wrestler may sometimes use their real name, or a minor variation of it, for much of their career, such as Angelo Poffo, Ernie Ladd, Verne Gagne, Bret Hart, and Randy Orton. Others can keep one ring name for their entire career (cases in point include Chris Jericho, Shawn Michaels, CM Punk and Ricky Steamboat), or may change from time to time to better suit the demands of the audience or company. Sometimes a character is owned and trademarked by the company, forcing the wrestler to find a new one when they leave (although a simple typeset change, such as changing Rhyno to Rhino, can usually get around this), and sometimes a character is owned by the wrestler. Sometimes, a wrestler may change their legal name in order to obtain ownership of their ring name (examples include Andrew Martin and Warrior). Many wrestlers (such as The Rock and The Undertaker) are strongly identified with their character, even responding to the name in public or between friends. It's actually considered proper decorum for fellow wrestlers to refer to each other by their stage names/characters rather than their birth/legal names, unless otherwise introduced. A professional wrestling character's popularity can grow to the point that it makes appearances in other media (see Hulk Hogan and El Santo) or even give the performer enough visibility to enter politics (Antonio Inoki and Jesse Ventura, among others).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How can a wrestler get around changing their ring name entirely?
Ah, so.. typeset change

Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who needs less knowledge and understanding about how DBMSs operate?
Ah, so..
